(Solved) Volvo S90 XC90 XC60 T6/T5 Vibration Issue SPA 2018 (AWD)
Hello everyone,
I had a noticeable vibration on my 2018 S90 T6 Inscription. The car was shuttering and vibrating heavily under acceleration or coasting at different speed (at 30K miles).
After inspecting and balancing the tires and wheels twice, as advised by the dealer, as usual. It turned out the axle shaft in the front right was the cause of the vibration. Easy to inspect by any qualified technician. The right side was moving while the other side wasn't. Check the below video and you will see the play in the axle.
The car was making the vibration since 24k miles and it was intermittent. I found the source of the vibration at around 30K miles, after it got worse & became permanent.
Update 1 :
The dealer diagnosed the car and found two issues:
1- The right drive axle had a play and needed to be replaced as expected
2- Front Prob drive shaft CV Joint is defective: The dealer showed me the new redesigned version where it is marked with a green line. If you don't see the green line on your prob shaft, this means you might have the old design one and will probably be defective.
Item#2 in the picture CV JOINT
propeller shaft.
Only for front CV joints. For rear CV joints the entire propeller shaft must be replaced. front.
Update 2 :thumbup::thumbup::thumbup:
Guys,
If you are facing this weird vibration, it's coming from the drive shaft (Propeller shaft front head) on AWD system. Check the last page in this technical journal. https://static.nhtsa.gov/odi/tsbs/2019/MC-10158649-9999.pdf
If your car doesn't have the green mark on the propeller shaft, it has to be replaced right away as it's most likely defective. The dealer replaced this part under warranty and the vibration in the cabin and drivetrain went away. However, I still have other vibration issues from two bent wheels and tire bubbles (20'' wheels sucks :thumbdown. Car mileage around 32K miles.
There is a rebuild kit #31492442 if your car out of warranty
